METHOD FOR CALIBRATING CRYOGENIC GYROSCOPE Russian patent published in 2007 - IPC G01C19/24 

FIELD: precision tool-making industry, possible use in cryogenic gyroscopic devices.

SUBSTANCE: method includes suspension of rotor in electrostatic suspension, transferring of angular speed to rotor, cooling of device down to superconducting condition, suspending of rotor in superconducting magnetic suspension and measurement of speed of deviations of cryogenic gyroscope. Suspension of rotor of cryogenic gyroscope in superconducting magnetic suspension is performed with enabled electrostatic suspension. Following condition is fulfilled: K_e/K_m=(H_s/E_s)·, where K_e, K_m - amplification coefficients of electrostatic and magnetic suspensions, E_s, H_s - supporting values of strengths of electric and magnetic fields in working space of suspension, μ_o, ε_o - magnetic and electric constants.

EFFECT: increased precision of calibration of cryogenic gyroscope by decreasing level of excitation momentums.
